细枝访问受保护/私有模型变量

请看一下 documentation . Twig没有访问受保护的变量,这是不可能的,但由于它的实现,它将转换您的Twig代码,例如。 foo.bar 到 $foo.getBar() 并检查该方法是否存在,因此它能够“访问”受保护的变量

从…起 Twig 的文档

为了方便起见 富。酒吧 在PHP上执行以下操作 图层:

- check if foo is an array and bar a valid element;
- if not, and if foo is an object, check that bar is a valid property;
- if not, and if foo is an object, check that bar is a valid method (even if bar is the constructor - use __construct() instead);
- if not, and if foo is an object, check that getBar is a valid method;
- if not, and if foo is an object, check that isBar is a valid method;
- if not, and if foo is an object, check that hasBar is a valid method;
- if not, return a null value.

foo['bar'] 另一方面,仅适用于PHP数组:

check if foo is an array and bar a valid element;
if not, return a null value.
